Aquaculture is a branch of industry that is engaged in rearing of fish, molluscs and crustaceans. Aquaculture grows and harvests animals and plants in almost all types of aquatic habitats, including oceans, lakes, rivers and ponds. Fish production in the European aquaculture in 2014. amounted to 2.341.667 tons. The largest producer in the European aquaculture is Norway with a production of 1.370.090 tons in 2014. The most reared species in European aquaculture in 2014. is the atlantic salmon (Salmo salar) with a production of 1.554.061 tons. Production of molluscs in European aquaculture is around 800.000 tonnes per year. The most reared types of molluscs are mussels (Mytilus galloprovincialis i M. edulis) and oysters (Crassostrea gigas i Ostrea edulis), and most of them are grown in France and Spain. Production in the Croatian aquaculture amounted to 13.916 tons in 2012. The total European aquaculture production is not sufficient to meet demand in the European market, and therefore large amounts of fish and seafood are imported.
